Taxonomy Comments: We need to more carefully study the plants ascribed to A. angustum in the Roan Mountain massif and other high elevation areas in the Southern Appalachians; they may represent an undescribed (or currently unrecognized) entity.

Other Comments: The occurrence of this northern species is not fully documented in NC or VA; it was found in the 1980s by Murray Evans on Hump Mountain, on or near the TN-NC border.
